ABSTRACT

An Interlocking System utilizing upper and lower grooves along the edges of the base of an item to interlock with upper and lower grooves on other items. One item described is a dispenser using a spongy material to force a tape with labels upwardly to be withdrawn. Another item with upper and lower grooves is a storage box.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to interlocking systems and more particularly to a system with a variety of items that interlock with one another at the base, such items including items for office usage, such as label dispensers but may be used equally well with kitchen and other items. This invention further relates to specific office equipment for use in the Interlocking System such as a label dispenser and a storage box or file cabinet with filing products.

[0003] 2. Prior Art

[0004] Frequently, various items are used together such as on a desk or in a kitchen. One item may, and often does, become separated and it is not uncommon for an item to be removed and then not be available when needed. This pertains to many different types of items of which office and kitchen equipment are just two.

[0005] A decided advantage would be achieved if various items could be connected in an orderly fashion but while permitting an item to be disconnected should the need arise to separate any one or more items while still preventing easy separation.

[0006] By way of example, one piece of office equipment that is advantageous to have available is a label dispenser. Labels are widely used. Many, such as return address labels are preprinted. Other labels are left blank to be filled in to meet a particular need such a labels used to identify food storage packages. Increasingly, labels have a sticky back and are dispensed from a tape on which they are mounted for ready removal when being put on just about anything which they are to identify. A dispenser, preferably a reusable dispenser, that permits ready access to labels and maintains them in storage for use would serve a need. An added benefit would be derived from a dispenser that can be annexed readily to or have annexed to it other items which have some relationship to it.

[0007] Another frequently used piece of office equipment is a storage cabinet. Whether used for file folders or the storage of various office devices such as pens and erasers, it is very helpful in an office. Like the label dispenser, it would be an added benefit to have a storage box that can be annexed readily to or have affixed to it other objects used in conjunction with it.

[0008] Objects

[0009] It is an object of this invention to provide an Interlocking System by which various items can be secured to one another.

[0010] It is a further object of this invention to provide an Interlocking System by which various items can be secured to one another while also being detachable from one another.

[0011] It is another object of this invention to provide a dispenser for the convenient dispensing of labels that is inexpensive and durable.

[0012] It is still another object of the present invention to provide a dispenser that can be secured to other items.

[0013] It is a further object of the present invention to provide an inexpensive and durable storage box that can be secured to other items.

[0014] These and other objects will be apparent to those skilled in the art based upon the description of the preferred embodiment.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0032] Referring now to FIG. 1, a storage box 11 is shown. The storage box 11 is mounted on a base 13. The base 13, which is shown as being rectangular, has four edges 15. Each of the four edges 15 has an upper groove 17 and a lower groove 19. The base 13 may be formed from two sheets 21, one on top of the other. A top sheet 23 would then have the upper grooves 17 and a bottom sheet 25 would have the lower grooves 19. In the alternative, a single sheet 27 may be used which would have formed from it either the upper groove 17 or the lower groove 19. Then the other groove, be it the upper groove 17 or the lower groove 19, would be affixed to the single sheet 27. This is shown in FIG. 3A where the single sheet 27 is shown with a lower groove 19 attached to it for the storage box 11 and with the item affixed to it having an upper groove 17 attached to the single sheet 27.

[0033] At each of the four edges 15, the upper groove 17 is turned up and away from the base 13 and over itself. Similarly at each of the edges 15, the lower groove 19 is turned down away from the base 13 and the upper groove 17 and under itself. The upper groove 17 and the lower groove are U-shaped with the U turned ninety degrees with both grooves 17, 19 open inside the edge 15.

[0034] The upper grooves 17 are best used to affix to the storage box or any other item also having upper grooves 17 and lower grooves 19, as shown in FIG. 1. The lower grooves 19 are best used to affix the storage box 11 or any other item having upper grooves 17 and lower grooves 19 to other units similarly equipped. In order to be able to affix other items to the storage box 11, the other items (as shown in FIG. 1) must also have similar mating lower grooves 19 and upper grooves 17. The upper grooves 17 and the lower grooves 19 are sized to be forced into similar grooves on connecting items and then are held in place by the tight fit while still being removable.

[0035]FIG. 3 shows the upper groove 17 of the storage box 11 blocked into a lower groove 19 of an ancillary item affixed to the dispenser and FIG. 4 shows the detail of the lower groove 19 of the storage box 11, which is used as an example, fitted into the upper groove 17 of an auxiliary item.

[0036] In FIG. 5, a different combination is shown as a label dispenser 29 is the central item rather than the storage box 11 and two auxiliary items are attached to it with the lower groove 19 of the auxiliary item being secured within the upper groove 17 of the label dispenser 29.

[0037] The variations of combination of items that can be secured together is virtually endless. As best seen in FIG. 4, FIG. 5, FIG. 7, FIG. 8, FIG. 9 and FIG. 10, the label dispenser 29 is shown. The labels 31 to be dispensed are mounted on a tape 33 which is folded back and forth (FIG. 6) in an accordion style. A holder 35 is secured to the base 13 of the label dispenser 29 at the lower edge 37 of two side walls 39, both of which are preferably solid but may have an opening. The side walls 39, which are substantially of the same size and generally parallel to one another, are sized to permit a pocket (not shown) to be affixed to hold a business card as the label dispenser 29 is very suitable as an item to be handed out for advertising purposes.

[0038] The holder 35 has ends 41 which may be either closed or left open. The ends 41 are shown closed in FIG. 5 and FIG. 10. From end 41 to end 41 and from the top edges 43 of the side walls 39 the holder 35 has a top 45. In the center of the top 45, substantially between the two ends 41, there is an opening 47 which preferably extends from side wall 39 to side wall 39. From the opening 47, the tape 33 with the labels 31 is dispensed and is also installed into the holder 35. However, when the ends 41 of the holder 35 are left open, installation of the tape 33 with the labels 31 can be achieved from either of the ends 41.

[0039] As seen in FIG. 5 and FIG. 7, a resilient member 49, which is formed from a sponge-like material, is located in the holder 35. The resilient member 49 serves as a spring permitting the tape 33 with the labels 31 affixed to it to be placed into the holder 35 on top of the resilient member 49 thereby compressing the resilient member 49 to a comparatively small thickness. As the tape 33 with the labels 31 are consumed, the resilient member 49 expands forcing the tape 33 with the labels 31 upwardly to be easily removed. The resilient member 49 has a bottom surface 51 which is secured to the base 13 of the holder 35 by any suitable adhesive. The resilient member 49 has a top surface 53 opposite from the bottom surface 51.

[0040] As best seen in FIG. 7, a plate 55 is affixed to the top surface 53 of the resilient member 49. The plate 55 is also affixed to the resilient member 49 by any suitable adhesive. A band 57 is mounted on the top of the plate 55 with a space between the plate 55 and the band 57. An end member 59 of the tape 33 with the labels 31 is slid under the band 57 thus holding the tape 33 with the labels 31 in place on the resilient member 49. When the tape 33 and the labels 31 are consumed, the end member 59 is removed and the end member 59 of a new stack of labels 31 on a tap 33 is inserted.

[0041] The storage box 11, which is shown in FIG. 1 is also shown in even greater detail in FIG. 11 and FIG. 12. The storage box 11 has a front side 61, a rear side 63, a left side 65 and a right side 67 as well as the base 13 having the upper grooves 17 and the lower grooves 19 as previously described. The storage box 11 also has a lid 69 and handle 71 which are detachable. The left side 65 and right side 67 as well as the front side 61 and the rear side 63 have a top edge 73 adjacent to the lid 69 and handle 71. The left side 65 and the right side 67 extend slightly above the front side 61 and the rear side 63. An inner channel 75 is formed in the left side 65 and the right side 67 immediately adjacent to the top edge 73 of the front side 61 and the rear side 63 and the inner channel 75 face one another being located on the inner faces 77 of the left side 65 and the right side 67. The inner channels 75 are immediately above the front side 61 and the rear side 63.

[0042] Also on the left side 65 and the right side 67, above the inner channels 75 are outer channels 79 which face away from one another being on the outside faces 81 of the left side 65 and the right side 67.

[0043] The lid 69, which is a flat sheet, slides in the inner channels 75. A tab 83 located on the lid 69 serves as a pull point for the lid 69. The handle 71 is a flexible member which narrows in the center section to form a hand grip 85 and expands to a left end 87 and a right end 89. At the right end 89 and the left end 87, the handle 71 bends inwardly and then back outwardly forming a protrusion 91 having a U-shaped but turned on its side with the closed ends of each U facing one another. The two protrusions 91 fit into the outer channels 79 and as the handle 71 is lifted up, the protrusions 91 are forced more securely into the outer channels 79.

[0044] As seen in FIGS. 11 and 12, a pocket 93 is located on the left side 65, the right side 67 and the front 61 of the storage box 11. These pockets 83 are transparent and are multi-purpose and may be used for advertising but can be used for posting information, such as frequently called telephone numbers. As shown in FIG. 12, a larger and more substantial enclosure 95 is provided on the rear side 63 to store the lid 69 when removed from the top 45 of the storage box 11.

[0045] As shown in FIG. 14, an inner box 97, which is retractable, is provided. The inner box 97 serves to take up unused space for files and to hold miscellaneous items. The inner box 97 has two ends 91 and a base 101. The base 101 includes upper grooves 17 and lower grooves 19, but only at the two ends 99, so the inner box 97 can be used outside the storage box 11 and can be affixed to it and to other items having upper grooves 17 and lower grooves 19. The base 101 is formed in two sections 107, each section 107 being affixed to a different end 99. One base section 107 has a series of clips 109 affixed to the lower surface 110 of the base section 107. The other base section 107 has one clip 111 mounted on its upper surface 113. Each clip 109 on the lower surface 110 (FIG. 15) mates with the one clip 111 on the upper surface 113 and the size of the inner box 97 is determined by which clip 109 on the lower surface 110 is enaged by the one clip 111.

[0046] In FIG. 13a file folder 115 is shown having pockets 117 which may be on either the interior or the exterior of the file folder 115 or on both the interior and the exterior of the file folder 115. Each pocket 117 is approximately half the size of the half of the file folder 115 on which it is located and each pocket 117 extends from the bend line 119 between the two halves of the file folder 115 with the opening into the pocket 117 being generally parallel to the bend line 119.
